PRODUCTION OF FRP-MADE HOLLOW MOLDED ARTICLE

摘要

PURPOSE:To obtain a method for controlling Vf and the weight of a molded article at a high accuracy for forming an FRP-made hollow molded article having a superior impact strength by an internal pressure molding method. CONSTITUTION:In an internal pressure molding method for an FRP-made hollow molded article, a reinforcing fiber layer and a shock absorber layer are provided between an internal pressure holding body to which an internal pressure is to be applied and an inner wall of a mold, and these layers are impregnated with a thermosetting resin and cured by the application of an internal pressure.
